Feature: showing off behave

  Background: user is lead to the login page
    Given user is lead to the login page

  Scenario: login invalid
    When I log in

我的目录结构是：

E:features\tutorial.feature
E:features\__init__.py
E:features\lib\__init__.py
E:features\lib\pages\__init__.py
E:features\lib\pages\login_page.py

文件“ steps / tutorial.py”，第8行，在从..lib.pages.login_page导入LoginPage KeyError：“'名称'不在全局变量中”

Answer 1

您很可能需要在导入路径中放入包名称：

from features.lib.pages.login_page import LoginPage

Answer 2

您能确认您没有相对进口吗？

作为缓解措施，您可以尝试在使用LoginPage之前将其导入。

@when("I log in")
    def step_impl(context):
    """
    :type context: behave.runner.Context
    """
    from ..lib.pages.login_page import LoginPage
    page = LoginPage(context)
    page.login()
